LG Washer Error Code LC

The LC code means the washer's leak detection sensor has found water in the base pan of the machine. The washer stops operation to prevent further water damage. This code can be triggered by actual leaks from hoses, loose components, or damaged parts, or in some cases by a faulty sensor giving a false reading. A thorough inspection of all hose connections, the drain pump filter, and the tub area is needed to identify the cause.

No, you should not continue running the washer while the LC code is active. The machine has detected a potential leak condition and has stopped to protect both itself and your home from water damage. Running the washer could cause water to spread into flooring or cabinetry. Address the source of the leak before resuming normal use.

Repair costs vary widely depending on the cause. If the fix involves reseating a hose, repositioning a component, or adjusting detergent usage, there may be no parts cost at all. Replacement parts such as a leak sensor, a damaged diaphragm assembly, or a broken tub fitting part typically range from around $15 to $80 depending on the component. If a technician is needed for diagnosis and repair, total service costs including labor can range from $100 to $300 or more.

Start by checking the base of the machine, all visible hoses, the detergent drawer connection, and the drain pump filter cover for any signs of water or loose fittings. Make sure you are using the correct type and amount of HE detergent, since excess foam can trigger the sensor. Reseat or tighten any components that appear out of place, dry out the base pan completely, and then run a short cycle to see if the code returns. If the code persists with no visible leak source, the leak sensor itself may need to be tested or replaced.

A reset may temporarily clear the LC code, but it will return if the underlying cause has not been corrected. The leak sensor in the base pan will trigger the code again as soon as water is detected. Clearing the code without fixing the leak or drying the base pan will not result in a lasting fix.
